	<h1>Phone number statistics</h1>
	<hr>
	
	Indicators in this group count phone numbers. They return the count for each phone number format.  
	<p>
	They validate the phone formats using the org.talend.libraries.google.libphonumber library.
	
	<p>
	<ul>
		<li>Valid phone number count: computes the valid phone numbers.</li>
		<p>
	    <li>Possible phone number count: computes the supposed valid phone numbers.</li>
		<p>
	    <li>Valid region code number count: computes phone numbers with valid region code.</li>
		<p>
	    <li>Invalid region code count. computes phone numbers with invalid region code.</li>
		<p>
	    <li>Well formed national phone number count: computes well formatted national phone numbers.</li>
		<p>
	    <li>Well formed international phone number count: computes the international phone numbers that respect the international phone format (phone numbers that start with the country code) .</li>
		<p>
	    <li>Well formed E164 phone number count: computes the international phone numbers that respect the international phone format ( maximum of fifteen digits written with a + prefix.</li>
		<p>
	    <li>Format Frequency Pie: shows the results of the phone number count in a pie chart divided into sectors.</li>
    </ul>
    
    <p>
